MADE IN USACARBIDE TIPPEDTOOL SELECTION BASICSDRILL SELECTION BASICS –• Carbide tipped drills are especially effective when production drillingabrasive cast irons and non-ferrous alloys.• Carbide tipped coolant drills perform exceptionally well in most steelsand all other materials.• The drill is an end cutting tool and as the point angle increases, thecutting edge becomes shorter, reducing corner wear as the cutting shearangle is reduced. Rock River provides two different point angles in mostdrill types. Select the larger angle for abrasive or tough materials.REAMER SELECTION BASICS –• Carbide tipped reamers are especially appropriate for close tolerancereaming. Because carbide is extremely resistant to wear, the reamer willproduce accurate hole size and smooth finish far longer.• The reamer is used to finish machine a previously formed hole to an exactdiameter with a smooth finish. It should not be used to significantlyenlarge a hole (max. 5% - depending on material and hardness).• The reamer is an end cutting tool, cutting only on the chamfer’s edge atthe outside diameter of the preformed hole. The standard 45° chamferangle provides effective cutting action for most materials.• Standard geometry reamers tend to follow the axis of the existing hole. Mis–aligned or crooked holes can be straightened by increasing the chamfer angle- sometimes a 180° flat end is very effective. This is a simple modification.COUNTERBORE SELECTION BASICS –• The counterbore is used to enlarge the end of a preformed hole when aflat bottom is required.• The counterbore is an end cutting tool which utilizes a pilot to align theenlarged hole being machined with the preformed hole.END MILL SELECTION BASICS –• END MILLS have cutting teeth on both end and side, permitting end cuttingand peripheral cutting. Center cutting types permit plunge and traversemilling.• CUTTING EDGE: Select sharp edged for faster speeds. Select radial edgedfor longer tool life.• SHANK DIAMETER: Select largest diameter available to maximize rigidityand minimize axial deflection and chatter.• NUMBER OF FLUTES: Select fewer flutes for milling softer materials athigher speeds and feeds where more chip space is required or whenmachine horsepower is limited.• Select more flutes for milling tougher materials at reduced speeds andfeeds or for increased table feeds using the same cutting speeds.• Deep holes, in excess of 3 drill diameters—use coolant feeding drills.• For drilling hardened steels, above Rc35—use straight flute die drills orcoolant type.• Use shortest tool available for accurate location and longer productionruns as rigidity is increased and runout minimized.• Core Drills are very effective for enlarging preformed holes, removing upto 30% of the tool diameter in all materials, including steel.• FLUTE AXIAL RELATIONSHIP:Straight Flutes - usual general purpose.Right Spiral Flutes - tend to bridge interruptions such as keyways, slotsor intersecting holes. Good chip clearing ability for ductile materials andblind holes.Left Spiral Flutes - also tends to bridge interruptions. Good for hard castiron, heat treated steels and other hard materials. Do not use in blind holes.• LENGTH OF CARBIDE - usually partial but full length carbide should beselected for deep holes and abrasive materials.• COOLANT FEEDING:Advantages - up to twice conventional feed rates will hold size muchlonger. Improved hole surface finish. Excellent chip disposal. Lubricatesand cools the cutting edge.Center Feed for blind holes. Flute Feed for through holes.• EXPANSION REAMERS - Economical for abrasive materials.• The three flute counterbore tends to reduce chatter & improve finish.• Many different shank options are available.• CUTTING DIAMETER: Select largest practical diameter to maximizerigidity, minimize chatter and improve tool life. If machine spindle speedis limited, the largest practical diameter permits higher cutting speeds.• FLUTE AXIAL RELATIONSHIP: Select straight flutes for usual generalpurpose.Select right spiral flutes for improved cutting action and easier chipremoval.Select left spiral flutes for use in absorbing impact shock when enteringsteel workpiece—maintains constant hold down pressure, and minimizeschatter.Select high spiral (15° or more) to dramatically improve cutting action,finish, chip removal and tool life. High spirals distribute impact loadmore evenly throughout the tool’s entire revolution.• COATINGS are especially effective.SLITTING SAW AND SIDE MILLING CUTTER SELECTION BASICS –• SLITTING SAWS can be used in deep slotting applications since they haveside clearance and side concavity on their carbide tips.• ARBOR DIAMETER: Select largest diameter available to maximize rigidity andminimize deflection. (A 1 1/4” arbor is more than twice as rigid as a 1” arbor.)• CUTTING DIAMETER: Select smallest diameter which permits two teeth tobe in contact with the workpiece throughout the tool’s entire revolution.If horsepower permits higher cutting speeds, but spindle speed is limited,select a larger cutting diameter.• NUMBER OF TEETH: Select coarse teeth for general purpose. Selectstandard teeth for better finishes.• TYPES OF MILLING: In conventional milling, the direction of the cutterrotation is opposite to the direction of the workpiece feed. The initialportion of the chip generated is very thin and gradually increasesthrough the cutting cycle. The maximum cutting force is upward at theend of the cutting cycle.• In climb milling, the direction of the cutter rotation and the direction ofthe workpiece feed are the same. The initial portion of the chip generatedis thick and gradually thins through the cutting cycle, producing abetter finish. The maximum cutting force is the initial downward thrustat the beginning of the cutting cycle.6 ROCK RIVER TOOL, INC. www.rockrivertool.com PHONE (800) 345-8924 FAX (800) 867-9312
